You'll be using several osnaps for this procedure. Rather than enter-
ing each osnap, you can activate any object snap by holding down the
Shift key and right-clicking in the drawing area. This opens a context
menu with all the object snap options shown earlier in Figure 4.50.
Selecting any of these options activates the osnap for a single pick.
You probably noticed the list of osnaps that appeared when you
right-clicked the Object Snap button in the status bar. These do not

5. Start the LINE command, and choose the Midpoint osnap from the
Shift+right-click context menu.

6. Place the cursor near the midpoint of the upper doorjamb line and
notice that the marker, now a triangle, appears when your cursor is
in the vicinity of the midpoint (see Figure 4.65).
A symbol with a distinctive shape is associated with each osnap.
Click when the triangle appears at the midpoint of the jamb line.
